[Octave-bug-tracker] [bug #60001] Unexpected OpenGL error message

[Nicholas Jankowski]

Follow-up Comment #8, bug #60001 (project octave):

As stated below, this is an error coming from your graphics driver. 

can you try with the soon-to-be-released Octave v.8.0.9.0? You can download
the installer from https://alpha.gnu.org/gnu/octave/ , scroll down to the
latest installers. Recommend choosing the same type you used for 7.3.0.

Recent versions of octave come with the option to switch opengl between a
hardware (on your system) and software (bundled) driver.  In v8, we've added a
small tool to switch between them. Assuming you use the executable installer,
there should be an OpenGL Switcher shortcut menu item.  Please try that, let
us know what it says for which version is currently being used, and try
switching it. Then let us know if the problem persists for either or both
cases.

(The above steps can be performed with 7.3.0 manually. While Octave is not
running, renaming the opengl32.dll file to opengl32.bak will force use of your
system hardware driver, restoring the dll will return to using the bundled
software driver. Assuming you used a 64bit installer, the file is located in
octave-home\bin\mingw64\opengl32.dll (see
https://docs.octave.org/v7.3.0/Hardware-vs_002e-Software-Rendering.html )
